Trump’s trade arguments got a boost with the WTO ruling on Thursday that China’s trade restrictions in agriculture were not in keeping with proper procedures. According to the WTO, the tariff-rate quotas imposed by China on rice, wheat and corn have several legal irregularities.

The US Department of Agriculture had previously estimated that China’s tariffs prevented crops worth $3.5 billion from being imported into China from the US. This ruling could have a positive impact on American farmers who could benefit from greater access into Chinese markets once this issue is rectified.

The Chinese Ministry of Commerce, on its part, has stated that it will review the WTO report and manage tariff-rate quotas on agricultural imports in keeping with WTO rules.
